Projector lamp bulb wire connecting structure

Abstract

The invention provides a projector lamp bulb wire connecting structure which comprises a wire connector, a lamp bulb joint and a wire component. The wire connector is connected with one end of the wire component, the lamp bulb joint is connected with the other end of the wire component and provided with a lamp bulb, the wire component comprises at least one lead, at least one sleeve and at least one terminal, the sleeves are connected on the peripheries of the leads in a sleeved manner and positioned at one end of the lamp bulb joint, and the terminals clamp and fix the leads from the outer sides of the sleeves and are connected with the lamp bulb joint. By arranging the sleeves at the end of the lamp bulb joint, heat resistance of a wire can be effectively improved, influences on convenience in use of the wire can be avoided, and purchasing cost of the wire can be lowered while more stability in connection is realized.

Description

technical field [0001] The invention relates to a projector bulb wire connection structure, in particular to a projector bulb wire connection structure capable of high heat resistance and stable connection. Background technique [0002] The light sources used in general projectors, such as tungsten-halogen lamps, metal halide lamps, ultra-high pressure mercury lamps, xenon lamps, etc., have a common characteristic of generating high heat. The high heat must be removed through the cooling device, otherwise it will affect the normal operation of the projector. At present, the heat dissipation device of the projector is usually provided with several cooling fans matched with each other on the casing of the projector, and a corresponding air duct is installed in the casing with respect to the setting of the fans, so that by all The air guide pipe guides the cooling airflow to flow through the light source and the parts that need to be dissipated, and discharges the heat energy ...

AI Technical Summary

Problems solved by technology

However, the wire used near the light source bulb must still pay special attention to the problem of heat resistance, otherwise there may be a danger of direct burning

Therefore, the high temperature resistant wire structure is used in the light source bulb module to prevent the wire from being damaged by high temperature. However, the higher the high temperature resistance level of the wire material, the hardness of the wire material will increase. The higher the heat resistance level of the wire material, the higher the cost. It will cause high hardness of the wire, inconvenient wire management and insufficient stability of the wire connection.

In order to solve such a problem, it is usually improved by using a wire with a lower heat-resistant grade and a heat-resistant sleeve outside the wire, but the structure of the heat-resistant sleeve on the outer edge of the wire will still make the wire The hardening of the wire does not have much effect on solving the above-mentioned problems of wire management or connection stability, so further improvement is still needed in the above-mentioned wire cost, wire management and wire connection stability
